if I was precipitate show me the solution

An example of a science pun,

"This", 
and it rattled as he shook it, "this, fugacious
trifler, is part of the dried liver of a man, who
 died in torment of Medea's broth five years
 ago."

At these words my bones were to be heard rattling within me, and I disappeared into the
 recesses of my shoes.

"Come forth," said my guide; "fear nothing.
 Come forth, or I will extract you chemically
 from those shoes of yours."

"Pardon me, if I was precipitate," I said, as 
I rose, "and show me the solution of this
 matter."
